The Global Oceanographic Data Center (GODAC) collected pictures of marine organisms around the coral reefs in the Ryukyu Islands from citizen divers during 2002 to 2013. GODAC also collected videos through GODAC’s research activities using a small remotely-operated vehicle “Niraikanai 150”. These image collection of the pictures and videos had been published on the website of Coral Reef Network WEB System (http://www.godac.jp/coral/). The image collection can become a valuable snapshot to know a past fauna or flora in the Ryukyu Island. The metadata of images provided to the system is used to extract scientific names and locations (latitude and longitude), which are then organized as biological occurrence records and published in BISMaL, a database for marine biodiversity information (http://www.godac.jamstec.go.jp/bismal/).
